    Abstract: Various non-limiting embodiments of the present invention relate to methods of processing alpha + beta or near-beta titanium alloys wherein the alloys are subjected to deformation above the beta transus temperature (T & ) of the alloys. The method of processing an alpha + beta or a near-beta titanium alloy comprises deforming a body of the alloy at a first temperature (T 1 ) that is above the T ß of the alloy; recrystallizing at least a portion of the alloy by deforming and/or holding the body at a second temperature (T 2 ) that is greater than T 1 ; and deforming the body at a third temperature (T 3 ), wherein T 1 >T 3 >T ß ; wherein essentially no deformation of the body occurs at a temperature below T ß during the method of processing the titanium alloy.

    Abstract: The application relates to the problem of alloying a melt, preferably a titanium melt, with oxygen by adding formed articles such as pellets containing a master alloy such as Ti02. The articles should fully and homogeneously disperse in the melt, while the carbon content of the melt should be kept below an allowable maximum, preferably below 0.04 wt. %. The formed article may also comprise iron or palladium. To solve this problem, the formed article consists of 70-82 wt. % of a master alloy and 18-30 wt. % of a high-carbon organic polymer such as ethylene vinyl acetate or a low density polyethylene. The homogeneous dispersion is achieved eg by the formed articles having a similar size as the other raw feed materials which are added to the melt.

    Abstract: A casting system and method. The casting system can include an energy source and a hearth, which can have a tapered cavity. The tapered cavity can have a first end portion and a second end portion, and the tapered cavity can narrow between the first and second end portions. Further, the tapered cavity can have an inlet at the first end portion that defines an inlet capacity, and one or more outlets at the second end portion that define an outlet capacity. Where the cavity has a single outlet, the outlet capacity can be less than the inlet capacity. Where the cavity has multiple outlets, the combined outlet capacity can match the inlet capacity. Further, the cross-sectional area of the tapered cavity near the inlet can be similar to the cross-sectional area of the inlet.

    Abstract: La aplicacion se refiere al problema de Alear una fusion preferentemente una fusion de titanio, con oxigeno mediante la adicion de articulos formados, por ejemplo, granulos que contienen una aleacion maestra, por ejemplo TiO2. Los articulos deben dispersarse completa y homogeneamente en la fusion mientras que el contenido de carbono de la fusion debe permanecer por debajo de un maximo permisible, preferentemente por debajo de 0.44% en peso. El articulo formado puede comprender tambien hierro o paladium. Para resolver este problema, el articulo formado consiste de 70 a 82% en peso por una aleacion maestra y de 18 a 30% en peso de un polimero organico con alto contenido de carbono como, por ejemplo, etileno-acetato y vinilo o un polietileno de baja densidad. La dispersion homogenea se logra, por ejemplo, mediante articulos formados que tienen un tamano similar a las demas materias primas alimentadas cuando se agregan a la fusion.

    Abstract: A system and method for continuous casting. The system includes a melt chamber, a withdrawal chamber, and a secondary chamber therebetween. The melt chamber can maintain a melting pressure and the withdrawal chamber can attain atmospheric pressure. The secondary chamber can include regions that can be adjusted to different pressures. During continuous casting operations, the first region adjacent to the melt chamber can be adjusted to a pressure that is at least slightly greater than the melting pressure; the pressure in subsequent regions can be sequentially decreased and then sequentially increased. The pressure in the final region can be at least slightly greater than atmospheric pressure. The differential pressures can form a dynamic airlock between the melt chamber and the withdrawal chamber, which can prevent infiltration of the melt chamber by non-inert gas in the atmosphere, and thus can prevent contamination of reactive materials in the melt chamber.
